Upgrading to New Releases

A plain Bugzilla is fairly easy to upgrade from one version to a - newer one. Always read the release notes to see if there are any issues - that you might need to take note of. It is recommended that you take a - backup of your database and your entire Bugzilla installation before attempting an - upgrade. You can upgrade a 'clean' installation by untarring a new - tarball over the old installation. If you are upgrading from 2.12 or - later, and have cvs installed, you can type cvs -z3 update, - and resolve conflicts if there are any. +>Upgrading Bugzilla is something we all want to do from time to time, + be it to get new features or pick up the latest security fix. How easy + it is to update depends on a few factors. +

There are also three different methods to upgrade your installation. +

  1. Using CVS (Example 5-1)

  2. Downloading a new tarball (Example 5-2)

  3. Applying the relevant patches (Example 5-3)

Which options are available to you may depend on how large a jump + you are making and/or your network configuration. +

Revisions are normally released to fix security vulnerabilities + and are distinguished by an increase in the third number. For example, + when 2.16.2 was released, it was a revision to 2.16.1. +

Point releases are normally released when the Bugzilla team feels + that there has been a significant amount of progress made between the + last point release and the current time. These are often proceeded by a + stabilization period and release candidates, however the use of + development versions or release candidates is beyond the scope of this + document. Point releases can be distinguished by an increase in the + second number, or minor version. For example, 2.16.2 is a newer point + release than 2.14.5. +

The examples in this section are written as if you were updating + to version 2.16.2. The procedures are the same regardless if you are + updating to a new point release or a new revision. However, the chance + of running into trouble increases when upgrading to a new point release, + escpecially if you've made local changes.

However, things get a bit more complicated if you've made - changes to Bugzilla's code. In this case, you may have to re-make or - reapply those changes. One good method is to take a diff of your customized - version against the original, so you can survey all that you've changed. - Hopefully, templatization will reduce the need for - this in the future.

From version 2.8 onward, Bugzilla databases can be automatically - carried forward during an upgrade. However, because the developers of - Bugzilla are constantly adding new - tables, columns and fields, you'll probably get SQL errors if you just - update the code and attempt to use Bugzilla. Always run the +>These examples also assume that your Bugzilla installation is at checksetup.pl - script whenever you upgrade your installation.

If you are running Bugzilla version 2.8 or lower, and wish to - upgrade to the latest version, please consult the file, - "UPGRADING-pre-2.8" in the Bugzilla root directory after untarring the - archive.

/var/www/html/bugzilla. If that is not the case, + simply substitute the proper paths where appropriate. +

Example 5-1. Upgrading using CVS

Every release of Bugzilla, whether it is a revision or a point + release, is tagged in CVS. Also, every tarball we have distributed + since version 2.12 has been primed for using CVS. This does, however, + require that you are able to access cvs-mirror.mozilla.org on port + 2401. + +

If you can do this, updating using CVS is probably the most + painless method, especially if you have a lot of local changes. +

+ 


bash$ cd /var/www/html/bugzilla
+bash$ cvs login
+Logging in to :pserver:anonymous@cvs-mirror.mozilla.org:2401/cvsroot
+CVS password: anonymous
+bash$ cvs -q update -r BUGZILLA-2_16_2 -dP
+P checksetup.pl
+P collectstats.pl
+P globals.pl
+P docs/rel_notes.txt
+P template/en/default/list/quips.html.tmpl
+

If a line in the output from cvs update + begins with a C that represents a + file with local changes that CVS was unable to properly merge. You + need to resolve these conflicts manually before Bugzilla (or at + least the portion using that file) will be usable. +

+ +

You also need to run ./checksetup.pl + before your Bugzilla upgrade will be complete. +

+

Example 5-2. Upgrading using the tarball

If you are unable or unwilling to use CVS, another option that's + always available is to download the latest tarball. This is the most + difficult option to use, especially if you have local changes. + 


bash$ cd /var/www/html
+bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.2.tar.gz
+Output omitted
+bash$ tar xzvf bugzilla-2.16.2.tar.gz
+bugzilla-2.16.2/
+bugzilla-2.16.2/.cvsignore
+bugzilla-2.16.2/1x1.gif
+Output truncated
+bash$ cd bugzilla-2.16.2
+bash$ cp ../bugzilla/localconfig* .
+bash$ cp -r ../bugzilla/data .
+bash$ cd ..
+bash$ mv bugzilla bugzilla.old
+bash$ mv bugzilla-2.16.2 bugzilla
+bash$ cd bugzilla
+bash$ ./checksetup.pl
+Output omitted
+

The cp commands both end with periods which + is a very important detail, it tells the shell that the destination + directory is the current working directory. Also, the period at the + beginning of the ./checksetup.pl is important and + can not be omitted. +

+ +

You will now have to reapply any changes you have made to your + local installation manually. +

+

Example 5-3. Upgrading using patches

The Bugzilla team will normally make a patch file available for + revisions to go from the most recent revision to the new one. You could + also read the release notes and grab the patches attached to the + mentioned bug, but it is safer to use the released patch file as + sometimes patches get changed before they get checked in (for minor + spelling fixes and the like). It is also theorectically possible to + scour the fixed bug list and pick and choose which patches to apply + from a point release, but this is not recommended either as what you'll + end up with is a hodge podge Bugzilla that isn't really any version. + This would also make it more difficult to upgrade in the future. + 


bash$ cd /var/www/html/bugzilla
+bash$ wget ftp://ftp.mozilla.org/pub/webtools/bugzilla-2.16.1-to-2.16.2.diff.gz
+Output omitted
+bash$ gunzip bugzilla-2.16.1-to-2.16.2.diff.gz
+bash$ patch -p1 < bugzilla-2.16.1-to-2.16.2.diff
+patching file checksetup.pl
+patching file collectstats.pl
+patching file globals.pl
+

If you do this, beware that this doesn't change the entires in + your CVS directory so it may make + updates using CVS (Example 5-1) more difficult in the + future. +
